Implement ES 2,3 parts of EXT_blend_func_extended for shader translation Exposes gl_SecondaryFragColor, glSecondaryFragData[] and gl_MaxDualSourceDrawBuffers to GLES SL 1.0. Relaxes rules for undefined output locations for GLES SL 3.0 and exposes gl_MaxDualSourceDrawBuffers. If the output GL context is GL ES 2.0 or 3.0: The emulation layer is expected to turn on EXT_blend_func_extended if the output GL context supports it. If the output GL context is GL: The emulation layer is expected to turn on EXT_blend_func_extended if the output GL context supports ARB_blend_func_extended or if GL context is 3.2 or later. If the source shader spec is GLES SL 2.0: The emulation layer is expected to inspect the shader compilation output variables upon linking. If output target is GL SL, the emulation layer should bind color location 0, index 1 to "angle_SecondaryFragColor" if variable "gl_SecondaryFragColorEXT" is used. Alternatively, emulation layer should bind "angle_SecondaryFragData" to locations 0,1,2,3,..., all color index 1, if "gl_SecondaryFragData" array is used. (The caller can not bind the locations or specify output variables.) If the source shader spec is GLES SL 3.0: The emulation layer is expected to do location auto-resolve of the the output variables that have undefined output locations that have not been bound by the caller. (The caller can not use gl_ built-ins, so nothing to do with those.)
